This thesis considers the human spatial occupational behaviour generically called 'settlement'. Within this process a diagnostic index of settlement is created to assist in analysing, defining, and exploring the parameters of 'Settlement Theory'. There is particular reference to Edward Gibbon Wakefield's Theory of Systematic Colonisation in South Australia, as it is one of the few Settlement Theories actually put into practice. Two case studies are examined to develop a transitional argument that connects theory to material outcome. Firstly, considering the macro implications of theory and material culture by comparing the implementation of Wakefield's theory (The South Australian Experiment) and the site, design, and Government Domain of the Capital (Adelaide). Secondly, by considering the micro effect of the theory on material culture in the form of the Governor's residence between 1836 and 1856, including search for the first Government House (Government Hut), to test the connection at this level.
